Title: Improvements relating to compressor thrust bearings
Inventor: PETRIE JAMES ALEXANDER
IPC: F01D3/04
Filed: 1961-08-10
Abstract: 965,465. Axial-flow compressors; gas turbine plant. ROLLS-ROYCE Ltd. Aug. 3, 1962 [Aug. 10, 1961], No. 28965/61. Headings F1C, F1G and FIT. In a compressor whose rotor is mounted on a shaft which is subjected to axial thrust and which is journalled within a thrust bearing, the thrust bearing being disposed within an inner casing of the compressor, a pressure responsive annular piston member carries or engages the thrust bearing and is axially movable with respect to the inner casing, and air compressed by the compressor is applied to a surface of the annular piston member to oppose the axial thrust. A gas turbine engine 10, which may be employed in a vertical lift aircraft, comprises a main compressor 11, combustion equipment 12, a high pressure turbine 13, and a low pressure turbine 14 mounted on a shaft 17. Gases passing through turbines 13, 14 are discharged downwardly through an outlet volute 16. An additional compressor 23 with its rotor 22 splined to the shaft 17 may be fabricated largely of synthetic resin materials with an inner casing 25 cast, for example from magnesium, and may supply air for the operation of blown flaps through an outlet diffuser 30. Thrust bearings 20, 21 support the shaft 17. Bearing 21 is mounted within an annular axially resilient diaphragm 31 which permits axial movement of the bearing 21. Air supplied through a gap 34, which may be provided by a leaky labyrinth seal, exerts a pressure on surface 35 of a piston 32, which is slidable in a sleeve 33 and which engages the bearing 21 at the rear, to oppose the axial thrust exerted by the turbine 14 and the compressor 23. The opposing thrust exerted by the piston 32 may be approximately equal to the thrust exerted by the compressor 23, the remaining thrust being absorbed by the bearing 20. The diaphragm 31 may be pre-stressed to increase the resistance to axial thrust exerted by the turbine 14 and compressor 23.

[Classes 75 (iii) and 75 (iv)] [Also in Group XXV] Means for locking together two adjacent fittings for tubular electric lamps in an end to end arrangement comprise a separate locking member engaged by one or more hook-like members on each fitting when the two fittings are brought into aligned contact with the locking member ; when the fittings have substantially flat end plates the locking member is a thin strip or plate which is sandwiched between juxtaposed end plates. When the locking member is suspended from a ceiling it. serves also to support the fittings. A locking member 9 comprises a thin strip 10 having a horizontal portion 11 and a supporting member 12 adapted to hold captive a bush for a depending conduit, the bush being free to rotate and move along a slot 15 in the member 12. Two downward hooks on an end plate 3 of a tubular lamp fitting 1 engage over the horizontal portion 11 of the locking member and enter slots in an end plate of an adjacent fitting 2 which is likewise provided with downward hooks 6 engaging the horizontal portion 11 and entering corresponding slots 7 in the fitting 1. Spring latches 13, 14 on the locking member engage the tops of the fittings. In a modification the supporting member 12 on the locking member 1 is replaced by a hook suitable for chain suspension. Specification 606,403 is referred to in the Provisional Specification.

Title: Improvements in or relating to the separation of metals
IPC: C22B9/02
Filed: 1936-10-26
Abstract: 483,675. Distilling metals. BYRNE, E. L. W. (American Smelting & Refining Co.) Oct. 26, 1936, No. 29085. [Class 82 (i)] A process for separating a mixture of metals which exhibits a single phase at one temperature and at least two liquid phases at a lower temperature, comprises simultaneously subjecting different portions of a bath of such a mixture to distillation and liquation while effecting thermosiphonic circulation between the said portions. In treating a molten bath of zinc and lead, the zinc is distilled from one portion of the bath maintained at a temperature slightly in excess of 900‹ C. while the second portion of the bath is maintained at not more than 500‹ C. to separate the zinc and lead into layers, intercirculation and exchange of metal being effected between the two portions so as to maintain the lead content of that portion undergoing distillation at a low value. The process is carried out in a furnace divided by a wall 18 into a liquation chamber 19 and a distillation chamber 20, which are connected by ports 21, 22 in the wall. The metal in the chamber 20 is heated by tubes 23 of refractory material which are fired internally and some of the hot gases from the tubes may be diverted through the opening 25 into the chamber 19, the rest passing into an exit flue. Zinc vapours from the chamber 20 are removed through a flue 30. The solid material is fed by a shoot 27 into the furnace where it is first melted. The process may also be applied to the separation of zinc and selenium, zinc and bismuth, zinc and thallium, and also sodium and magnesium.

Title: Improvements in the manufacture of organic esters of cellulose
IPC: C08B3/02
Filed: 1947-10-31
Abstract: Cellulose esters are manufactured by esterifying cellulose with the anhydride of a lower fatty acid in the presence of a solvent for the cellulose ester formed, using as catalyst during the esterification between 0.8 per cent and 10 per cent of sulphuric acid and between 0.2 per cent and 2 per cent of perchloric acid, both calculated on the weight of the cellulose. The lower fatty acid is an unsubstituted mono-carboxylic acid containing not more than 4 carbon atoms. Preferably the proportion of sulphuric acid used is about 0.8-6 per cent and of perchloric acid about 0.2 and 1.5 per cent.  The solvent for the cellulose ester may be the esterifying acid and/or another solvent such as methylene chloride.  The cellulose may be cotton, cotton linters, or a purified wood pulp having an alpha-cellulose content preferably above 90 per cent; it is preferably pretreated with lower fatty acid and perchloric or formic acid before esterification.  After esterification the cellulose ester may be ripened.  The production of esters with acetyl values of 57-58.5 per cent and 61-62.5 per cent is referred to in particular, and cellulose acetate, propionate, butyrate, acetate-propionate and acetate-butyrate are mentioned.  In one example, cotton was pretreated with acetic acid and perchloric acid and added to a cooled mixture of acetic acid, acetic anhydride and sulphuric acid.  After an hour aqueous acetic acid was added and the mixture ripened at 45 DEG  C. for 22 hours (sulphuric acid may be added).  The cellulose acetate obtained had an acetyl value of 57 per cent.  In another example, cotton was pretreated with acetic acid and formic acid and added to a mixture of acetic anhydride, acetic acid, perchloric acid and sulphuric acid.  After 2 1/2 hours aqueous acetic acid was added and allowed to stand for 1 hour at 50 DEG  C.  A cellulose triacetate of acetyl value above 62 per cent was produced.  Specifications 531,014, 538,913, 566,863, 568,047, 568,098, 581,157, 597,295 and 620,726 are referred to.

Abstract: 1,040,160. Semi-conductor switching circuits. AUTOMATIC TELEPHONE & ELECTRIC CO. Ltd. July 16, 1963 [July 31, 1962], No. 29404/62. Heading H3T. [Also in Division G4] Operation of detector contacts in a vehicle axle counter produces a voltage across a diode which is substantially constant for a wide range of detector-circuit currents. The system may operate with a range of A.C. or D.C. potentials. Closure of contacts D.C. produces a substantially constant potential across silicon rectifiers MR1, MR2 to charge C2, so cutting off the normally conducting transistor TR1 and making transistor TR2 conduct. Meter MTR is thereby energized. At the end of the pulse C2 delays reapplication of - ve potential to TR1 whereby contact bounce does not result in faulty counts. If the current duration is excessive capacitor C1 becomes fully charged to prevent re-operation of the counting circuit. If current leaks across contacts D.C. while they are open resistor R1 prevents the development of potential sufficient to operate the counter. If several detectors and counters operate from a common source they are isolated by rectifiers MR4, MR5.
